Electric motor with arcuate pole pieces

Claim 1

AN ELECTRIC MOTOR ROTATABLE ABOUT AN AXIS OF ROTATION AND OPERATING ON THE PRINCIPLE OF MAGNETIC ATTRACTION ONLY, COMPRISING IN COMBINATION: (A) A PLURALITY OF ENERGIZE STATOR MEANS EACH COMPRISING A PAIR OF MAGNETIC UNITS, EACH UNIT HAVING A CORE AND AN ENERGIZING WINDING FOR SAID CORE, MEANS CONNECTING THE CORES OF EACH OF SAID PAIRS WITH EACH OTHER TO FORM A FLUX PATH BETWEEN SAID CORES, THE UNITS OF A PAIR BEING MOUNTED IN SAID MOTOR IN SPACED RELATION IN AN AXIAL DIRECTION, EACH UNIT OF A PAIR PROVIDING A SAME GIVEN POLARITY EACH TIME IT IS ENERGIZED AND THE UNITS OF A PAIR OF PROVIDING POLES OF COMPLEMENTARY POLARITIES WHEN ENERGIZED; (B) A PLURALTIY OF SAID STATOR MEANS MOUNTED IN SPACED CIRCUMFERENTIAL RELATION, SAID STATOR MEANS BEING UNEVEN IN NUMBER; (C) A ROTOR COMPRISING A PAIR OF MEMBERS ARRANGED IN SPACED RADIAL RELATION, SAID MEMBERS BEING ARCUATE SUCH THAT THE RELUCTANCE THEREOF DECREASES IN THE DIRECTION OF ROTATION, SAID MEMBERS BEING POSITIONED AND DIMENSIONED TO HAVE A PATH OF ROTATION ADJACENT TO SAID STATORS; (D) MEANS MOUNTING SAID ROTOR MEMBERS FOR MOVEMENT IN A GIVEN DIRECTION RELATIVE TO SAID STATOR MEANS, AND SAID ROTOR MEMBERS BEING MOUNTED CLOSER TO SAID AXIS THAN SAID STATORS; (E) SAID ROTOR MEMBERS BEING DIMENSIONED AND POSITIONED IN SAID MOTOR TO HAVE ONE SIDE THEREOF ATTRACTED BY ONE SIDE OF THE MAGNETIC UNITS OF A PAIR AND THE OTHER SIDE THEREOF CONCURRENTLY ATTRACTED BY THE OTHER SIDE OF THE MAGNETIC UNITS OF A PAIR; AND (F) COMMUNTATOR MEANS ELECTRICALLY CONNECTED TO SAID MAGNETIC UNITS FOR SELECTIVELY ENERGIZING AND DEENERGIZING SAID STATOR MEANS IN RESPONSE TO THE RELATIVE POSITION OF SAID STATOR MEMBERS TO SAID STATOR MEANS TO CAUSE SAID STATOR MEANS TO MAGNETICALLY ATTRACT SAID ROTOR MEMBERS AS SAID MEMBERS MOVE IN A DIRECTION TOWARD AND ADJACENT SAID STATOR MEANS AND TO TERMINATE OR CUT-OFF SAID ATTRACTION WHEN SAID ROTOR MEMBERS MOVE IN A DIRECTION AWAY FROM SAID STATOR MEANS.
